Question

Quizplus · Accepted Answer

Cardinality is implied by the use of symbols in Crow's Foot notation. The symbols used include a circle for zero, a line for one, a crow's foot for many, and a double line for a specific number (e.g. two). Attributes and tables are used to represent entities and their properties, but they do not imply cardinality. Images may be used for visual representation, but they do not convey specific information about cardinality.
